One of the best video lecture series I have come across is the Aircraft Systems Engineering course from MIT. If you haven't watched these yet, I highly suggest you do. All of the speakers used to be heavily involved with the development of the Space Shuttle Orbiter.
As regards the question in your final paragraph, close votes happen when a question is outside the site topic as described in the Help Centre:
What topics can I ask about here?
Space Exploration is primarily about spacecraft, how to send them to space, and their functions there. Specifically, questions on these topics are encouraged:
There is also a playlist with 11 hours of video in 45 sections on YouTube called Engineering Mathematics YouTube Workbook, by Dr Chris Tisdell
The Workbook that goes with this course is available on Bookboon (it is an ad-supported free pdf download)
And the Jet Propulsion Laboratory has a downloadable video primer on orbital mechanics. It lasts about 90 ...
Here is another video from Glenn Research Center showing many different slow-motion camera angles from STS-114, STS-117, and STS-124. The commentators discuss each angle in detail, explaining what is happening in the launch sequence and the purpose of different structures on and around the Shuttle during launch. There is a wealth of information here. Ascent -...
Two things I think might help:
The close function could maybe use a new option:
Do a search for [blank] to answer this question.
This prevents getting drawn into a discussion of how the question could be phrased better or narrowed down when really the issue is it isn't worth spending time answering because that would take time away from more thoughtful ...
